The latter, or if min=0 and max=-1.

The min and max define the permitted range, and are inclusive (a value of
exactly the min or the max is permitted).

min max -> meaning, "display text"
0 -1 -> must have exactly 0 running, "found X, req. none"
1 -1 -> must have 1 or more running, "found X, req. 1 or more"
0 0 -> must have exactly 0 running (ie, not running), "found X, req. at
most 0"
0 1 -> must have zero or one instances, "found X, req. at most 1"
1 1 -> must have exactly 1 running, "found X, req. between 1 and 1"
0 3 -> must have no more than 3 running, but can have as few as zero,
"found X, req. at most 3"

As Larry said, -1 is only special when it is a maximum.
